BlueOptics Q28-AOC-1M-AT-BO InfiniBand fibre optic cable 1m QSFP28 Male

The BlueOptics Q28-AOC-1M-AT-BO InfiniBand fibre optic cable is a 1 metre active optical cable (AOC) with QSFP28 male connectors on both ends. Designed for high-speed links, it follows QSFP28 MSA form-factor conventions and supports 100GBASE-SR4 multi-mode optical transmission for short-reach, high-bandwidth interconnects in data centres and HPC environments. The cable integrates optical transceivers and electronics in a pre-assembled, factory-terminated assembly to provide a plug-and-play connection between compatible QSFP28 ports.

Advantages

The integrated AOC design eliminates the need for field-terminated fibres or patch cords and reduces insertion losses associated with manual splicing. Built to MSA-compatible QSFP28 mechanical and electrical specifications, the cable provides a compact, hot-pluggable solution for 100 Gbps links and simplifies rack-to-rack and device-to-device connections. Digital diagnostic monitoring (DDM/DOM) functionality is available to report parameters such as optical power and temperature when the host hardware supports it.

Suitable for

• Short-reach 100 Gbps interconnects in data centres and server rooms
• High-performance computing (HPC) clusters and switch-to-switch links
• Storage systems and high-density aggregation panels with QSFP28 ports

Key specifications

• Length: 1 metre
• Connector type: QSFP28 male to QSFP28 male
• Transmission standard: 100GBASE-SR4 (multi-mode optical)
• Cable type: Active Optical Cable (AOC) with integrated transceivers
• Supports digital diagnostic monitoring (DDM/DOM) when host hardware provides support

How to use

Install the BlueOptics Q28-AOC-1M-AT-BO by inserting each QSFP28 plug into the corresponding QSFP28 port on your devices while the equipment is powered and supports hot-pluggable modules. Verify physical seating by gently pressing until the connector latches. Ensure both ends are connected to compatible QSFP28 ports that support 100GBASE-SR4 or equivalent multi-mode QSFP28 interfaces. If DDM/DOM status is required, check that the host device exposes diagnostic data for the port.

Usage recommendations

Handle the cable by the connector housings and avoid tight bends near the connectors; maintain the minimum bend radius specified by the manufacturer. Use in environments and hardware certified for QSFP28 AOC operation and verify host compatibility before deployment. For troubleshooting, inspect DDM/DOM readings and confirm both link partners are configured for the same multi-mode 100G standard.
